IMPROITEMENT IN COTTON-SEED HLLERS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all Iwhom it 'may concern:

Be it known that I', J ons D. SEILLMAN, of Memphis, in the county ofShelby, in the State of Tennessee, haveiuvented a new and improvedCotton-Seed Huller; and I do hereby declare that the following is afull, clear, and exact description of the construction and operation ofthe same, reference being had to the. annexed drawings, making .a partof this specification, in which- Figure l is a vertical section.

v Fig-ure 2, a section ofthe drum.

A, cylinder.

, B B, drum.

C, grooves.

D, steel bars on cylinder A.

E, steel bars on drum BB.

G, grooves in the drum'B B.

F, axle.

H, drive-wheel.

I, small wheel on the end ofthe axle F.

K, fan.

1 J, bolt.

L, hopper.V

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation. ,i

I construct a cylinder out of cast-iron, cast-steel, or other suitablemateriahconical at one end, terminating in a plane cylinder at theother, as shown at A in ig. l of' the accompanying drawings, and uponthe conical. part of the cy1inder,I form grooves G, with sharp edges,which I place at a greater or less angle to the axis. of the cylinder.

` Upon the plane portion of the cylinder, I fasten, by means ofgroovesout in the cylinder, steel bars D, with square cutting-edges. l `Thesebars are placed obliquely upon the face ofthe cylinder.

I construct a drum, B B, to t upon the cylinder A, so as to enclose it,leaving a small space between the cylinder and drum, for the passage ofthecottonseed while undergoing the hulling-process.

Upon the inside of the drum I form grooves G and oars E, correspondingwith those formed upon the cylinder, placing them, however, at anopposite angle to those upon the cylinder;

shell from the seed, with as little crushing of the ker-- nel ofthe seedas possible.

Another object accomplished by this manner of arranging the grooves andbars, is the rapid feeding of the machine.

The cylinder D is made fast upon the axle F. Motion is in'lparted by thedrive-wheel H acting upon the small wheel I.

The drumB B is prevented from turning with the motion of the cylinder,by being made fast to the frame P.

For the purpose of separating the kernel of the seed from the shell, Iprov-ide a bolt, J, constructed out ot" wire cloth, or other suitablematerial, and attach it to the axle F, so as to join close upon thecylinder.

The seed, in passing through the hulling-process, will drop into thebolt.

Upon the inside of the bolt I construct a fan, K, with propeller-shapedtlangesLarranged so as` to produce, with the turning of the axle, acurrent of air through the bolt, so as to blow the shells and lint ofthe seed through the open end of the bolt.

The operation of this machine will be very simple.

The `seed are placed in the hopper L, and will pass in between the drumand cylinder, and pass out into the bolt, husked.

What I claim as my invention, and desire to secure by Letters Patent,is-

The cotton-seed huller, as shown, composed of the cylinder A with itsbars D and grooves C, drum B with bars E and grooves G, and the bolt J,and propeller-shaped fau K, all constructed, arranged, and operatingsubstantially as and for the purpose herein set forth. Y

JOHN D. STILLMAN.
